Accuton C173-6-191, 6.5″ Ceramic Mid/Bass
Accuton C173-6-191 6.5″ Ceramic Cone Mid/Bass
The C173-6-191 is a 6.5″ inch bass-midrange for small bookshelf monitors or slim floor standers. The medium sized voice coil with 38mm titanium voice coil former provides high midrange resolution. The long excursion is for high SPL capabilities. Consider this as a successor to C173-6-095, but with higher excursion and smaller box size. This driver might be interchangeable with the C173-6-095 using the same crossover.
- Overhung motor design
- 38mm Titanium VC former
- Soft high shape rubber surround
- Vented VC, pole piece and former
- Improved spider, surround and voice coil former for extended excursion ans smooth roll off
- Vented box design parameters:
